1. General information
1.1. How to properly use this manual
This installation and maintenance manual has been written to assist the user with proper procedures when
handling, installing, operating, and maintaining the equipment. All the safety warnings and instructions in
this book must be followed to prevent injury to personnel.
This manual must be kept for future reference during installation, operation, and maintenance.
1.2. Safe motor operation information
WARNINGS: High voltage and rotating parts can cause serious or fatal injuries. Qualified personnel should perform
installation, operation, and maintenance of electrical machinery. For equipment covered by this instruction book, it is
important to observe safety precautions to protect personnel from possible injury. Be sure to keep the installation and
maintenance information for future reference. All warning and cautions must be followed.
Installation
• Avoid contact with energized circuits and rotating parts.
• Avoid bypassing or rendering any inoperative safeguards or protective devices.
• Avoid use of automatic-reset thermal protection where unexpected starting of equipment might be hazardous to personnel.
• Avoid contact with capacitors until safe discharge procedures have been followed.
• Be sure the motor shaft key is captive before the motor is energized.
• Avoid long exposure near machinery with high noise levels.
• When the motor is coupled to equipment, ensure that system vibrations are within acceptable limits (per ISO
10816-1) to avoid failure of the motor.
• Use proper protective gear, care, and procedures when handling, lifting, installing, operating, and maintaining the motor.
• If eyebolts are used for lifting motors, they must be securely tightened, and the direction of the lift must not exceed a 15°
angle from the shank of the eyebolt.
• Do not use the motor shaft as a means for lifting.
• Do not lift both the motor and driven equipment with the motor lifting means.
• Do not stand on or place objects on the motor.
Maintenance
Safe maintenance practices performed by qualified personnel are imperative. Before starting maintenance
procedures, be positive that:
• Equipment connected to the shaft will not cause mechanical rotation.
• Main motor windings and all accessory devices associated with the work area are disconnected from electrical power
sources.
• The motor has been given time to cool.
Failure to properly ground the frame of the motor can cause serious injury to personnel. Grounding should be in accordance
with National and local Standards and consistent with sound practice.
These instructions do not purport to cover all the details in motors nor to provide for every possible contingency to be met in
connection with installation, operation, or maintenance. Should further information be desired, or should problems arise
which are not covered sufficiently for the purchaser’s purposes, the matter should be referred to EMRAX directly.
